With Panos leaving academia and joining Microsoft to pursue his career in the industry, Nick has kindly accepted to step in to replace him as my supervisor for the last year of my PhD.
I'm looking forward to working with Nick. His work is an inspiration (Nick's thesis is one of the best I've read) and I hope we'll be successful working together.

What is Cloud?
After hearing so much about Cloud Computing [1], a few months ago I decided to find my own answers...
You can find these in this document: What is Cloud? [2] Named after the famous “What is Grid? A three point check” [3]. I don't expect my document to reach such a high level of visibility, but it might start a few discussions...
Following is a short teaser:
I start by introducing distributed computing and Grid because, frankly said; I didn't think there was anything new in Cloud. However, the principal points I’m trying to make in this document are:
We’ve reached such a high level of complexity and size in distributed systems that more and more tasks should be managed automatically.
Computing resources are not only the usual data or processor time anymore, but could be anything.
I’ll follow the discussions over on wiki and in the different events I’ll attend because these two points are at the base of my work.
More on this later as I am working on some exiting stuff related to Cloud and security…(did I hear security in Cloud computing?!).

Highlands roadtrip
Following AHM [1], Anna and I went on a roadtrip in the highlands. From Edinburgh to Inverness, followed by Gairloch, Ullapool and Stoer (amongst other destinations). It was a blast, we saw so many nice things like seals, baskin sharks or wonderfull landscapes...still 641 miles (1000km+) in 4 days is a lot.
We're both looking forward to go there again!

Committee
It's now official, I'm member of the technical committee for the MESH 2009 event. This year's event was a blast, both in term of content, with some interesting work presented, and in term of networking with amazing researchers from a lot of big companies (Siemens, Nokia, Cisco, Thales, Atos Orgin...) and universities.
I got to know Andreas and Marcel, and I'm please to see they're both committees as well. I'm looking forward to more interaction with them.
Finally, a little advertising for my own paper :) Secure & Rapid Composition of Infrastructure Services in the Cloud (here).

UK e-Science ALL HANDS MEETING 2008
Last week I was present at the AHM in Edinburgh. Amongst other cool things were talks from Andrew Martin and from Ross Anderson. Andrew's defence of the fact that security specialists should work together to come up with practical solutions (e.g. patterns, guidelines, scenarios) rather than work in their own corner was spot on.
The AssessGrid project demo along with the poster by Karim Djemame were also interesting. I'm working on similar issues of negotiation of non functional properties and I hope to have the chance to discuss more of this with Karim in the futur.
John and Paul's talks [1, 2] went well and it was good to see what they've been up to in more details.
Finally, my talk [3] went rather well, although I was disapointed by the low attendence.
[1] A Peer-to-Peer Database Server based on BitTorrent
[2] An Adaptive Distributed Query Processor for e-Science using Dynamic Service Deployment
[3] A semi autonomic infrastructure to manage non functional properties of a service

Exploits of a mum
This SQL injection joke makes me laugh...Plus I wouldn't be surprised if that would really happen.

ESB : Technical Report
It's been a very long time since my last post, but I found the motivation to start again. To let you know that I authored a technical report on ESB. You can find this one here (http://www.cs.ncl.ac.uk/publications/trs/abstract/1037).
Please feel free to comment here or send me an email if you have any comment or suggestion. Following is the abstract:
Please feel free to comment here or send me an email if you have any comment or suggestion. Following is the abstract:
Currently, business requirements for rapid operational efficiency, customer responsiveness as well as rapid adaptability are driving the need for ever increasing communication and integration capabilities of the software assets. Enterprise Application Integration (EAI), which is the process of integrating enterprise systems with existing applications and in general distributed computing, have produced diverse integration techniques and approaches to undertake these challenges. This has brought the development of Service-Oriented Architecture (SOA) variants, which is partly supported by commonly accepted standards that ensure interoperability, sharing and reusability. As a result of this, a safer and faster level of return on investment (ROI) can be generated while inter-software communication and integration has becomes ever easier. In this paper we discuss ESB and evaluate the concept against already existing broker architectures and paradigms.
